Ahh yes. The gain vs distortion thing. Lots of folks think high gain is always for brutal metal but not necessarily. Angus and Malcolm Young used tons of gain but not much distortion, especially in the early days. Gain can create distortion sure but they are not mutually exclusive. I really enjoy lot's of gain with a hint of distortion for my rhythm playing. I am not that much of a lead player so when I do solo I need distortion and compression to pull it off (pun intended) convincingly. I like PPIMV and FX loops because I like to crank up the master and use either channel volume or pre-gain knob for overall volume. yeah it's touchy that way with most amps but once you hit it right, it's heavenly. Alternately sometimes I like to use the FX loop to push the power section hard.
